Abstract

Systems and methods for compensating for visual distortion caused by surface features on a display are disclosed. For example, one disclosed system includes: a display including one ore more surface features; a processor configured to: receive a display signal including graphical data; determine a location of the surface feature; transform the display signal based at least in part on the location of the surface feature; and cause the transformed display signal to be displayed.

Claims

1. A system, comprising:

a display comprising a surface;

a processor coupled to the display; and

a memory comprising program code that is executable by the processor to cause the processor to;

receive a display signal comprising graphical data;

generate a surface feature at the surface of the display by transmitting a first electrical signal to a haptic substrate coupled to the display, the haptic substrate being configured to receive the first electrical signal and responsively deform in shape to generate the surface feature;

cause the surface feature to move along the surface of the display by transmitting a second electrical signal to the haptic substrate;

determine a movement of the surface feature along the surface of the display;

transform the display signal based at least in part on the movement to generate a transformed display signal; and

transmit the transformed display signal to the display.

2. The system of claim 1, wherein the surface feature is one of a plurality of surface features arranged on the surface according to a predetermined shape.

3. The system of claim 2, wherein the predetermined shape comprises one or more letters or numbers, a grid shape, a spiral shape, a web shape, a swirl shape, or a button shape.

4. The system of claim 1, wherein the processor and the surface are disposed within a mobile phone, a portable digital assistant, a portable media player, or a portable gaming device.

5. The system of claim 1, wherein the memory further comprises program code that is executable by the processor to cause the processor to transform the display signal by modifying a contrast, a hue, a sharpness, a brightness, a resolution, or a saturation of the graphical data.

6. The system of claim 1, wherein the surface feature does not correspond to the graphical data.

7. The system of claim 1, wherein the movement of the surface feature along the surface of the display comprises a continuous movement of the surface feature from a first location on the surface to a second location on the surface.

8. The system of claim 1, wherein the surface is a touch-screen.

9. A method comprising:

receiving, by a processor, a display signal comprising graphical data;

generating, by the processor, a surface feature at a surface of a display by transmitting a first electrical signal to a haptic substrate coupled to the display, the haptic substrate being configured to receive the first electrical signal and responsively deform in shape to generate the surface feature;

causing, by the processor, the surface feature to move along the surface of the display by transmitting a second electrical signal to the haptic substrate;

determining, by the processor, a movement of the surface feature along the surface of the display;

transforming, by the processor, the display signal based at least in part on the movement to generate a transformed display signal; and

transmitting, by the processor, the transformed display signal to the display.

10. The method of claim 9, wherein the surface feature at least partially forms one or more letters or numbers, a grid shape, a spiral shape, a web shape, a swirl shape, or a button shape on the surface.

11. The method of claim 9, further comprising:

transforming the display signal by modifying a contrast, a hue, a sharpness, a brightness, a resolution, or a saturation of the graphical data.

12. The method of claim 9, wherein the processor and the surface are each part of a mobile phone, a portable digital assistant, a portable media player, or a portable gaming device.

13. The method of claim 9, wherein the surface feature does not correspond to the graphical data.

14. The method of claim 9, wherein the movement of the surface feature along the surface of the display comprises a continuous movement of the surface feature from a first location on the surface to a second location on the surface.

15. The method of claim 9, wherein the surface is a touch-screen.

16. A non-transitory computer readable medium comprising program code, which when executed by a processor is configured to cause the processor to:

receive a display signal comprising graphical data;

generate a surface feature at a surface of a display by transmitting a first electrical signal to a haptic substrate coupled to the display, the haptic substrate being configured to receive the first electrical signal and responsively deform in shape to generate the surface feature;

cause the surface feature to move along the surface of the display by transmitting a second electrical signal to the haptic substrate;

determine a movement of the surface feature along the surface of the display;

transform the display signal based at least in part on the movement to generate a transformed display signal; and

transmit the transformed display signal to the display.

17. The non-transitory computer readable medium of claim 16, further comprising program code which when executed by the processor is configured to cause the processor to:

transform the display signal by modifying a contrast, a hue, a brightness, or a saturation of the graphical data.

18. The non-transitory computer readable medium of claim 16, wherein the processor and the surface are each part of a mobile phone, a portable digital assistant, a portable media player, or a portable gaming device.

19. The non-transitory computer readable medium of claim 16, wherein the surface feature does not correspond to the graphical data.

20. The non-transitory computer readable medium of claim 16, wherein the movement of the surface feature along the surface of the display comprises a continuous movement of the surface feature from a first location on the surface to a second location on the surface.

21. The non-transitory computer readable medium of claim 16, wherein the surface is a touch-screen, and wherein the touch-screen and the display collectively form a touch-screen display.
